Abstract

The invention relates to a vehicle steering system and a pure electric sanitation vehicle. The pure electric sanitation vehicle comprises the steering system, the steering system comprises a steering wheel, a steering wheel rotating shaft, a rotating angle sensor and an electromagnetic resistance device, and the electromagnetic resistance device comprises an electromagnetic coil and a magnetic part fixed on the steering wheel rotating shaft; the electromagnetic coil is correspondingly attracted with one magnetic pole of the magnetic part after being electrified, and the electromagnetic coil and the corresponding magnetic pole are arranged along the radial direction of the steering wheel rotating shaft; and the electromagnetic resistance controller is used for controlling the electromagnetic coil to be electrified to attract the corresponding magnetic part after the vehicle speed exceeds a set value v and the steering wheel angle alpha exceeds a set value. The electromagnetic resistance controller can control the electromagnetic coil to generate resistance to the steering wheel rotating shaft, reduce the reciprocating swing angle of the steering wheel, improve the stability of the steering wheel and solve the problem that an existing steering wheel is poor in stability.

本发明涉及车辆转向系统及纯电动环卫车，纯电动环卫车包括转向系统，转向系统包括方向盘、方向盘转轴、转角传感器、电磁阻力装置，电磁阻力装置包括电磁线圈和固定在方向盘转轴上的磁性件，电磁线圈通电后与磁性件的一个磁极对应相吸，电磁线圈与对应的磁极沿方向盘转轴径向布置；电磁阻力控制器用于在车速超过设定值v且方向盘转角α超过设定值后控制电磁线圈通电与对应磁性件相吸。电磁阻力控制器可以控制电磁线圈对方向盘转轴产生一个阻力，减小方向盘往复摆动角度，提高方向盘的稳定性，解决了目前的方向盘稳定性差的问题。
